Up-regulation of the α-Secretase Pathway

An arthritogenic alphavirus uses the α1β1 integrin collagen receptor
2005
Ross River (RR) virus is an alphavirus endemic to Australia and New Guinea and is the aetiological agent of epidemic polyarthritis or RR virus disease. Here we provide evidence that RR virus uses the collagen-binding alpha1beta1 integrin as a cellular receptor. Infection could be inhibited by collagen IV and antibodies specific for the beta1 and alpha1 integrin proteins, and fibroblasts from alpha1-integrin-/- mice were less efficiently infected than wild-type fibroblasts. Soluble alpha1beta1 integrin bound immobilized RR virus, and peptides representing the alpha1beta1 integrin binding-site on collagen IV inhibited virus binding to cells. We speculate that two highly conserved regions with…

α-Conotoxins EpI and AuIB switch subtype selectivity and activity in native versus recombinant nicotinic acetylcholine receptors
2003
The Xenopus laevis oocyte expression system was used to determine the activities of alpha-conotoxins EpI and the ribbon isomer of AuIB, on defined nicotinic acetylcholine receptors (nAChRs). In contrast to previous findings on intracardiac ganglion neurones, alpha-EpI showed no significant activity on oocyte-expressed alpha3beta4 and alpha3beta2 nAChRs but blocked the alpha7 nAChR with an IC50 value of 30 nM. A similar IC50 value (103 nM) was obtained on the alpha7/5HT3 chimeric receptor stably expressed in mammalian cells. Ribbon AuIB maintained its selectivity on oocyte-expressed alpha3beta4 receptors but unlike in native cells, where it was 10-fold more potent than native alpha-AuIB, had…
NT-3 in cardiovascular pathologies
2019
La NT-3 y su receptor TrkC son puntos clave en la formación del corazón y los vasos durante la etapa embrionaria. Sin embargo, el papel de la NT-3 como modulador de las funciones cardiovasculares en la edad adulta no ha sido investigado con detalle. El objetivo de la presente Tesis es determinar la expresión de NT-3 y TrkC en el sistema cardiovascular humano y de roedores, así como el papel de la vía NT-3/TrkC como moduladora de las funciones cardiovasculares y su relación con las enfermedades a este nivel. Para ello, se cuantificó la expresión génica y proteica de NT-3 y TrkC, en tejidos humanos y de roedores, así como en células humanas cardiacas y aorticas. Los resultados muestran que lo…
Monotherapy with indacaterol once daily reduces the rate of exacerbations in patients with moderate-to-severe COPD: Post-hoc pooled analysis of 6 mon…
2014
Summary Background In patients with COPD, exacerbations are associated with poor quality of life and may shorten survival. Prevention of exacerbations is, therefore, a key objective in COPD management. Indacaterol, a once-daily ultra-long-acting β 2 -agonist, has been shown to reduce exacerbations in various studies. This pooled analysis evaluated the effect of indacaterol on exacerbations versus placebo. Methods Six-month data were pooled from three randomized, double-blind, and placebo-controlled studies: indacaterol 300 μg versus placebo (1 year); indacaterol 150 μg and 300 μg versus placebo (6 months); and indacaterol 150 μg versus placebo (6 months). All treatments were administered on…
